Nearest charts (0.12/0.24) agree directly; distant charts (0.12/0.36) do not (task JS ≈ 0.071–0.082), yet low-complexity transition maps calibrated on an independent seed pass 5/6 directions per family on the primary protocol — the weak direction is 0.36 → 0.12 (latent JS ≈ 0.017–0.021 > 0.01). Transition coherence is not robust across secondary seeds (mean pass ≈ 0.53–0.67).",
